Suppose a 95% confidence interval for a population proportion is (0.30, 0.60). Rewrite this interval in the form of margin of error.

This interval in the form of margin of error is expressed as 0.45 ± 0.15.

p = 0.45

MOE = 0.15

Step-by-step explanation:

A confidence interval is calculated from a sample statistic (in this case, a sample proportion) and substracted or added a margin of error (MOE) for the lower and upper bound respectively.

This can be expressed as:

If we substract the upper bound from the lower bound, we can calculate the margin of error as:

With this information, we can calculate the sample proportion p:

Then, we can express the confidence interval as:
